The Breitling Superocean Automatic 42 (Reference A17366) is a professional-grade Swiss dive watch originally introduced in 2019. It bridges the gap between rugged utility and contemporary luxury styling. Known for its exceptional depth rating and relatively slim wrist profile, it remains a highly regarded timepiece on the secondary luxury watch market. The 42mm stainless steel case features polished flanks contrasting with satin-brushed lugs. At roughly 13.3mm thick, it sits remarkably flat and wears comfortably, given the 500 metre depth rating. There is a 120-click unidirectional ratcheted bezel with a matte rubber infill incorporating raised, satinated numerals rather than modern ceramic, giving it a tactile, tool-watch aesthetic. A screw-down crown with two gaskets guarantees the impressive 500m of water resistance. The dial features large, highly legible Arabic numerals at 6, 9 and 12, paired with broad baton markers. It proudly displays the classic Breitling "winged" logo. A cambered sapphire crystal coated with heavy anti-reflective (AR) treatment on both sides makes the glass nearly invisible under direct lighting conditions. The watch is powered by Breitling's Calibre 17, a modified ETA 2824-2 automatic movement operating at 28,800 vibrations per hour (4Hz). It features a quick-set date function at 3 o'clock, stop-seconds (hacking), and 25 jewels. The watch was sold on a stainless steel Professional III bracelet—featuring asymmetrical links with a single-fold flip-lock clasp.

This example is in immaculate cosmetic and mechanical condition, and is offered as a complete set with Breitling's new style eco-friendly box, with card holder, travel pouch, Quick-Start Guide and Warranty Card.
